Title: Planar type optical waveguide, planar type optical waveguide having bragg grating, and production of the planar type optical waveguide
Inventor: LOESCH KURT DR
IPC: G02B6/13
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to form many Bragg's gratings varying in Bragg's wavelengths in the extremely limited space with arbitrary constitution by patterning and forming a cladding layer in such a manner that the Bragg's gratings are directly engraved at a core by irradiation with light. SOLUTION: This optical waveguide has the core COR and the two buffer layers BUF, CLA. The buffer layers BUF, CLA have the characteristic that their respective refractive indices are lower than the refractive index of the core COR. Consequently, the light coupled within the core COR is guided into the waveguide. The cladding layer CLA is provided with surface patterns. The patterns GST have the form of striped recesses of the direction perpendicular to the direction of the optical waveguide. The coherent rays falling onto the patterns GST from above are refracted by the recesses, by which optical interference patterns are formed in the core COR of the waveguide as well under these patterns.

Title: Method and implement for detection of liquid
Inventor: IWASE KENICHI
IPC: G01V8/12
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To easily detect a liquid in a trace amount by a method wherein light is made incident in a specific angle range with reference to a normal line on the surface of a flow passage, reflected light or transmitted light is received on the surface of the flow passage so as to measure its intensity and the existence of the liquid inside the flow passage is detected. SOLUTION: An upper plate 11 and a lower plate 12 are formed of a transparent material, a flow passage 8 is formed on the plate 12, and an incident face 14 and a radiant face 15 are formed on the plate 11. Light at an incident angle 17 in a range of about 42 to 60 deg. with reference to the normal line 16 of the flow passage 8 is transmitted vertically through the incident face 14, it is reflected on the surface 13 of the flow passage, it is transmitted vertically through the radiant face 15 so as to be received by a photodetector, and the existence of a liquid inside the flow passage 8 is detected. When the flow passage is filled with the air and the liquid flows into a part on which the light is incident inside the flow passage at an angle at which the light is reflected totally, the light is not reflected totally.  Consequently, when a change in reflected light is detected, the existence of the liquid even in a trace amount inside the flow passage can be detected easily.

Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To reduce a transient current at the time of system interconnection by utilizing a capacitor for improving an existing power factor and installing the capacitor for improving a power factor into a feeding system before installing an induction generator. SOLUTION: In a closing control circuit, a 30m sec timer and five 10m sec timers are connected in series, and a composite closing operation circuit for closing and opening use is provided in each of six capacitors for improving a power factor. Since all of the composite closing operation circuits are identical, the circuit constitution of a composite closing operation circuit 14 is exemplified on behalf of them. When a current flows into either of the closing circuit 14-1 and the opening circuit 14-2 of the composite closing operation circuit 14, so that either of a closing coil 14b and an opening coil 14f is excited, a switch is closed or opened, so that a capacitor for improving a power factor is connected to a system or disconnected from it.  Therefore, a transient current can be suppressed only by once closing the capacitor at the time of system interconnection by utilizing an existing phase advance capacitor group.

Title: Hot air heater
Inventor: OSHIMA AKIRA
IPC: F24H3/04
Filed: 1988-12-19
Abstract: PURPOSE:To restrict an influence against a temperature of hot air and reduce a temperature at a duct side surface by a method wherein a partition plate is placed within the duct so as to close a part of an inlet of a cold air passage composed of the partition plate and the duct side surface. CONSTITUTION:Air 12 from a propeller fan 3 is mixed with combustion gas 13 generated from a burner 5 and blown out of a blowing port 8 as hot air. The propeller fan 3 rotates in a clockwise direction and the combustion gas 13 of high temperature coming out of a combustion cylinder 6 is displaced to a right side of the duct 2. However, since the interior of the duct 2 is partitioned by the partition plate 10 into a hot air passage 14 and the cold air passage 11, the hot combustion gas 13 may not touch directly the side surface of the duct 2. In addition, the partition plate 10 may shield a radiation heat from the combustion cylinder 6. Accordingly, it is possible to reduce a temperature at the right side of the duct 2.

Abstract: PURPOSE:To maintain the effect of lighting and eliminate an ugly appearance caused by the reflection from an illuminated body as well by covering an illuminating lamp with a translucent cover, and mixing an optic ray diffusing material with a translucent main material comprising said translucent cover. CONSTITUTION:Several stages of shelves 19, on which merchandises 18 are displayed, are formed inside an insulated box 6 of a low temperature show case. An illuminating lamp 31 of an illumination device 1 and an translucent cover which covers then are integrally mounted with the lower part of the shelves 19 with a fixture 20. A fluorescent lamp is used as the illuminating lamp 31 while a cover 31 is cylindrically shaped. An optic diffusing material is mixed with a translucent main material forming a main section 35 of the cover 32, thereby forming a diffusion section 36. The light emitted from the illuminating lamp 31 is refracted and changes its direction when it comes upon the cover 32. When the light comes upon the optic diffusion material, it is further refracted. When it comes out from the cover 32, it is diffused and turned into light. This construction makes it possible to produce soft illumination without glittering and diffuse the refraction to merchandise on display so that visual observance may be improved.
